How to choose between LEGION, CORE and MICRO in 2025
Three combat lines of NEMESIS for different missions: LEGION - standard infantry cycles, CORE - assault under 5.56 (with CORE I3 version for barrel integration), MICRO - ultra-compact for CQB and vehicles. What goes where.

Three combat lines of NEMESIS for different missions. All three - steel + phosphate coating, dual-circuit gas-off-loading system, flash suppression. The difference is in calibers, dimensions, and use-case logic. You don't choose the "best model" - you choose the one that fits your mission.
Combat lineup

LEGION
The base combat line for standard infantry missions. 470 g, 39.5 mm, 180 mm. Calibers: 5.45 / 5.56 / 7.62. Handles 6+ magazines in a row. The balance of price and service life - for where you need reliability with no surprises.

CORE
Assault under 5.56. LEGION dimensions (470 g / 39.5 mm / 180 mm), different internal geometry. Two versions: CORE S - classic muzzle-mount, CORE I3 - integrated with 30 mm barrel extension. For those where total system length is critical.

MICRO
Ultra-compact. 350 g, 39.5 mm, 120 mm. Calibers: 5.45 / 5.56 / 9 mm. 60 mm shorter and 120 g lighter than CORE/LEGION. For CQB, vehicles, confined spaces - where dimensions are the deciding factor.
How a combat NEMESIS works
All three feature a dual-circuit gas-off-loading system. On firing, gas is split between the main channel and an outer circuit that diverts part of the flow before it reaches the main volume. The result: reduced backpressure, flash suppression, and a predictable bolt group cycle. Not ZERO (ZERO is exclusive to ARCANE - its gas dynamics deliver almost complete flash invisibility), but the dual-circuit system is more than sufficient for combat cycles.
What a suppressor delivers in combat cycles
- Muffled report instead of a sharp crack - lower chance of revealing your position.
- Flash suppression after the first shots - less signature at distance.
- Predictable cycle - a second accurate round arrives faster.
- Cleaner breech after a series - the action's service life lasts longer.
How to choose for your mission
Standard infantry, AK/AKS - LEGION. Assault work on 5.56 - CORE (choose between muzzle-mount and integrated configurations). CQB, crews, vehicles, where every centimeter and every gram counts - MICRO.
Calibers: .223, 5.45x39, 5.56, 7.62x39, 9 mm - depending on the model. We build to fit your platform.
